Equivalent & Substitute Parts for 13AT471-T2

Part Overview

The 13AT471-T2 is a toggle switch manufactured by Honeywell Sensing and Productivity Solutions, configured as a Double Pole Double Throw (DPDT) panel mount switch with momentary-off-momentary (Mom-Off-Mom) switching function. This component is rated for 5A at 115V AC and 28V DC, featuring a flatted actuator and solder turret termination. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 13AT471-T2 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must be DPDT
• Switch function must be Mom-Off-Mom
• Current rating must support minimum 5A
• Voltage rating must accommodate both AC and DC operating conditions
• Termination style must be solder turret for PCB integration

Mechanical Compatibility Requirements:

• Mounting type must be panel mount
• Actuator type must be flatted
• Panel cutout dimensions must be circular 12.40mm diameter
• Bushing thread must be 15/32-32
• Illumination status must be non-illuminated

Compliance Requirements:

• RoHS compliance status must match or exceed the original specification
• MSL rating must be 1 (Unlimited) or equivalent

The 12TW401-7 qualifies as a substitute part based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

The 12TW401-7 is an active production substitute for the obsolete 13AT471-T2. Both components are manufactured by Honeywell Sensing and Productivity Solutions and share identical circuit configuration (DPDT), switching function (Mom-Off-Mom), current rating (5A), mounting type (panel mount), mechanical interface dimensions, and termination style.

The 12TW401-7 operates at 125V AC, which exceeds the 115V AC rating of the original part, providing operational margin in AC applications. The actuator length differs by 1.01mm (17.27mm versus 16.26mm), which remains within typical mechanical tolerance for panel-mounted toggle switches with identical bushing threads and panel cutout specifications.

Both parts carry RoHS compliance certification and MSL rating 1 (Unlimited), ensuring compatibility with modern manufacturing and storage requirements. The 12TW401-7 provides additional specifications including operating temperature range (-65°C ~ 71°C) and environment sealed ingress protection, neither of which were documented for the original part.

For applications requiring DC voltage operation, the original 13AT471-T2 specification of 28V DC should be confirmed against actual system requirements, as the 12TW401-7 does not specify DC voltage rating in the provided data.

Frequently Asked Questions (FAQ)

Q: Can the 12TW401-7 directly replace the 13AT471-T2 in existing designs?

A: The 12TW401-7 is mechanically and electrically compatible for panel mount applications. Both parts feature identical DPDT configuration, Mom-Off-Mom function, 5A current rating, flatted actuator, solder turret termination, 12.40mm circular panel cutout, and 15/32-32 bushing thread. The 1.01mm difference in actuator length does not affect panel mounting compatibility. Confirm DC voltage requirements if the application operates at 28V DC, as this specification is not provided for the substitute part.

Q: What are the key differences between these parts?

A: The 13AT471-T2 is obsolete; the 12TW401-7 is in active production. The substitute operates at 125V AC (versus 115V AC) and includes environment sealed ingress protection and documented operating temperature range (-65°C ~ 71°C). The original part's DC voltage rating (28V) is not specified for the substitute.

Q: Are both parts RoHS compliant?

A: Yes. Both the 13AT471-T2 and 12TW401-7 are RoHS compliant with MSL rating 1 (Unlimited), meeting current environmental and manufacturing standards.

Q: Does the actuator length difference affect installation?

A: No. The 1.01mm difference in actuator length (16.26mm versus 17.27mm) does not affect panel mounting compatibility, as both parts use identical panel cutout dimensions (12.40mm circular) and bushing thread specifications (15/32-32).

Q: What termination method do these switches use?

A: Both parts use solder turret termination, suitable for direct PCB soldering without additional connectors or adapters.
